NLDQ5-400/4P
Dual power automatic transfer switch is an automatic transfer switch that integrates switch and logic control, truly achieving mechanical-electrical integration. It is suitable for industrial and enterprise distribution equipment with frequency of AC SOHz, rated voltage up to 440V and agreed current up to 1600A. It has functions such as voltage detection, communication interface, electrical and mechanical interlocking, etc; it can achieve full automation, remote control, mandatory setting of "O", emergency manual operation, and is widely used for automatic conversion of main power supply and backup power supply in power supply systems, or automatic conversion and safe isolation of two load devices. The switch is managed by various logic commands issued by the control circuit board to the motor, which drives the operating mechanism of the main part of the switch to quickly connect and disconnect the circuit or perform circuit conversion, achieving safe isolation through a clearly visible state.
